Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed January 30. 1907 Serial No. 354,827.

To all whom it may concern:

Be it known that I, JOSEPHINE ANTOINETTE CARON, (wife of B. O. BELAND,)a subject of the King of Great Britain, residing at the city anddistrict of Montreal, in the Province of Quebec, Canada, have inventedcertain new and useful Improvements in Pegging- Machines; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to pegging machines; the object of my invention isto provide a machine adapted for use in securing materials together bymeans of pegs of wood or of other material which may be softer or harderthan wood, such as leather or zinc.

A further, more specific, object is to provide a construction in apegging machine which is less noisy and which will permit the use ofsofter pegs than known forms, by having the throat bear constantly onthe work which is passing between it and the anvil, so that there is nospace left between the throat and the work in which the peg may becomebent or twisted.

A further object is to provide means for mounting the splitting andcutting knives separately from each other, so that the splitting knifeis worn and dulled only by passing through the ribbon from which thepegs are out.

A further object is to provide means for preventing the ribbon, fromwhich the pegs are cut, from crowding on the splitting knife, whichworks directly through the ribbon and into a slot, rather than. againstan abutment plate; which would. dull and wear the splitting knife.

A further object is to provide a construction adapted to upset a peg sothat it assumes a doubly curved form, thereby strengthening the plies ofmaterial which are secured together by the pegs.

My invention consists, generally, of the construction, combination andarrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming part of this application, I haveillustrated one form of embodiment of my invention, in which drawingssimilar reference characters designate corresponding parts, and inwhich:

Figure 1 is a side elevation of a known form of machine, showing theapplication. of my invention; Fig. 2 is a front elevation of the head ofthe machine, showing the attachment of the improvements of my invention;Fig. 3 is a horizontal section taken approximately on line 33 of Fig. 2,and showing the construction of the throat, the cutting knives and theircooperating parts; Fig. 4 is a fragmentary detail in section takenapproximately on line 4-4 of Fig. 3, showing the relative positions ofthe ribbon and the guard plate which prevents the ribbon from crowdingon the splitting knife; Fig. 5 is a fragmentary detail in frontelevation of a portion of the head illustrating the throat actuatingmechanism with the other parts removed; Fig. 6 is a fragmentary detailshowing in rear perspective the awl and hammer plate or bar; Fig. 7 is afragmentary detail in left-hand side elevation of the throat; Fig. 8 isa fragmentary detail, in front elevation, of the ribbon guide nextadjacent the throat; Fig. 9 is an enlarged vertical section through twoplies of work, showing the peg in elevation; Fig. 10 is a fragmentarydetail, in vertical section, through one form of an anvil head; and Fig.11 is a fragmentary detail, in vertical section, through a modified formof anvil head.

The general construction of the illustrated machine is known to be old,and is the construction illustrated in myUnited States Patent No. 735,499, which I hold by assignments, and the parts known to be old, sofar as practical in the following specification, have been designated byreference letters, while the parts which are new are designated byreference numerals. I In the construction shown in said patent, it isimpossible to use pegs softer than wood, because of the play which isgiven the throat, or the distance which normally separates the work fromthe throat.

Referring to the drawings, A designates a frame adapted to support arotatable oscillatory and vertically adjustable anvil B, the verticalmovement of which is adapted to be controlled by the foot lever C. Arock shaft D is adapted to oscillate the anvil B, through the medium. ofa connecting rod E actuated from the upper shaft F, carrying the fastand loose pulleys G. Mounted on the front end of the shaft F, is apulley H, formed with a grooved cam I.

Rollers J, carried by the laterally rockable head K, are ada ted tocontact with the cam j on the shaft F, so as to give the head itslaterally rocking movement.

A connecting rod L extends from the foot lever'to a toothed bell cranklever M, adapted to reciprocate a rod N, which cooperates with the pegmoving mechanism to regulate the length of the peg. The reciprocation ofthe peg moving mechanism is accomplished by a roller N attached to thepeg moving mechanism and adapted to be engaged and moved by the camsurface N of the rod N which is reciprocated as above stated. Thisconstruction is clearly set forth in Figs. 1 and 2.

A solid arm 0 is secured to the upper portion of the frame A, and hasthereona hanger P.

A vertically reciprocable bar Q is disposed on the front face of thehead, and is adapted to be reciprocated vertically by means of theroller 9 carried thereby, and running in the grooved cam I. The bar Qcarries the awl g and the hammer g A vertically reciprocable rod R isnormally maintained in depressed position by suitable resilient means,and is provided with a lug r, cooperating with the rod N which isslightly tapered, and also carries the hooked finger r inserted in thethroat and adapted to actuate the pegs downward so that they may be cutthe desired length by the cutting knife. The length of the movementdownward of the rod R is entirely dependent upon the position of the rodN, which in turn is positioned'by the foot lever C connected to theanvil B over which the work passes. As the anvil B is depressed byincreased plies of work passing between it and the throat, the rod N isactuated rearwardly, permitting less downward movement of the rod R, andconsequently the pegs which pass into the throat are cut onger to suitthe requirements of the work at that time under the throat.

A cover plate S is disposed over the face of the head K, and the ribbonguide T provided with an abutment plate T is disposed on the side of themachine and is adapted to guide the ribbon U of suitable material, suchas wood, leather, metal, &c., which is actuated forward by the feedrolls V.

Provided in the head K, is a recess 1, in which is disposed a link 2,pivoted at its up per end as at 3, and having connected to its ower enda link 4:, as by means of the pivot 5. The link 4 rides in a recess 6 inthe head K, so that it is guided in its movement when actuated by thelink 2. The lower end of the link 4 is pivoted as at 7 to the upper endof the throat 8, having a vertical bore 9 and an opening 10 in one sidecommunicating with the vertical bore 9 and adapted to permit the pegs topass into said vertical bore.

The anvil B is perforated at 11 to receive the removable head 12, whichremovable head is provided with a bore 13 coinciding in position andsize with the awl g so that no ateral movement of the awl g ispermitted, as the head K and anvil B are reciprocated simultaneously.The direct advantage of having the awl and the bore 13 of the same sizeis that the awl will not become easily broken on account of its nothaving any play, and the replacing of awls is a considerable item ofexpense to the manufacturer. The removable head 12 in the form shown inFig. 10 is provided with a sharpened annular flange 14 adapted for usewith pegs of metal, so that the lower end of the peg is split andriveted while being bent, while the form shown in Fig. 11 is providedwith a flange 15 of rounded contour adapted for use in connection withpegs of wood, and more especially of leather which is soft, and the endsof which are easily upset.

The head K is provided with a vertical slot K in which the bar Q isadapted to work, and the rear side of the bar Q is provided with a lug17 disposed in the inclined slot 16 of the link 2. As the bar Q isreciprocated by means of the roller 9, the link 2 is reciprocatedlaterally, causing a vertical reciprocation of the throat 8, but thepressure of the lug 17 on the wall of the slot 16 maintains the throatconstantly on the work while the peg is being driven, thus preventing asoft peg 18 from being bent, twisted or broken, as when it leaves thethroat it must enter the work W. The bar Q being positively actuated,the hammer 9 travels farther than the throat 8, so that it forces thepeg 18 entirely into the work, and the reciprocatory movement of thehead K and the anvil B causes the peg to assume the shape shown in Fig.9. It will be understood that the forward movement of the work in thedirection of the arrow X of Fig. 5 is caused by the lateralreciprocation of the head K, while the awl g is in lowered position.

A knife block 19 is partly supported by the hanger P, and is providedwith a slotted shank 20 adjustably secured to a portion of the frame Aby means of the bolts'21. The knife block is provided with a face 22 onone side, which is disposed vertically and at right angles to the ribbonU, from which the pegs are cut, while the other side of the block isprovided with a vertical face 23 disposed at an angle to the face 22.This face 23 is at an angle also to the ribbon U.- Disposed on the face22 of the knife block, is a cutting knife 24, the same width as the peg,the length of which is to be cut thereby. The knife 24 is maintained inposition by means of the guide 25 of ordinary construction.

A splitting knife 26 is secured to the face 23, and works through a slotZ in the supplementary ribbon guide 2, which is secured to the side ofthe frame A. The splitting knife 26 passes through the slot Z into therecess 27 formed in the side of the frame A, so that the splitting knife26 does not contact with an abutment plate or similar part, and does notbecome dulled except by contact with the ribbon U. To prevent the ribbonfrom crowding into the recess 27 in the operation of the machine, aplate 28 is secured to the frame A as by means of the bolts 29, so thatwhen the head K is rocked laterally, the ribbon U is pressed against thesplitting knife 26, and a peg severed, and the feed of the ribbon U forthe moment stopped.

Suitable means may be used to actuate the feed rollers V to withdraw theribbon U the thickness of the knife 26, to give more perfect movementthereof. The head being oscillated back, the ribbon is again fed topresent a suitable width of peg to be cut.

For the purpose of raising the rod R which carries the hooked bar rextending into the throat 8, the upper end of the rod r is provided witha hooked portion 30 adapted to be engaged by the cam 31 carried on thefor ward end of the shaft F. A suitable spring 32 is carried by theribbon guide T, between the lower end of which and the abutment plate Tthe peg passes into the slot 10 of the throat 8.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is
